Web29 nov. 2024 · It is easy to apply Newton's law of cooling with our calculator. Just specify the initial temperature (let's say 100 °C), the ambient temperature (let's say 22 °C), and the cooling coefficient (for … WebThe thermal time constant is given by the following equation, τ th = ρV C hAS τ t h = ρ V C h A S. Where, ρ = Density of the body. V = Volume of the body. C = Specific heat of an object. h = Convective heat transfer coefficient. As = Surface area of the body. Therefore thermal time constant depends on the above factors. WebThe temperature-vs-time graph for the decomposition of H 2 O 2 (aq). The calorimeter initially contained 50.0 mL of 0.921 M H 2 O 2.
